External GPS and WAN Antennas
The primary requirement for any coaxial cable used with the external GPS or WAN antenna is to
have less than 5 dB of attenuation at 1.5 to 1.8 GHz for the entire length of cable, including
connector losses.
You may use any type of 50 ohm coaxial cable as long as the total loss, including connectors, is
less than 5 dB at 1.5 to 1.8 GHz.
Itron recommends using regular 1/2" coax or Times Microwave LMR-400.
If the antennas are mounted in an exposed outdoor environment, you must provide lightning
protection and proper grounding. For more information on lightning protection and grounding,
see Lightning Arrestor on page 27, Grounding the Antenna System on page 25, and the
Motorola R-56 guidelines.
Antenna Sweep Test
After remote antenna installation, perform an antenna system sweep test and verify the VSWR
(voltage standing wave ratio) does not exceed 1.5:1. For more information, see Performing an
Antenna Sweep Test on page 88 and the Antenna Line Sweeps Procedure on page 94.
Caution: All coaxial cable used to connect an antenna to the collector or repeater
must be properly grounded at the top and bottom of the coaxial line. Additionally, any
cable lengths of 200 feet or greater must be grounded each 100 feet. For more
information, see Lightning Arrestor on page 27.
Antenna Connectors
Connectors for the 915 MHz and WAN antenna cables must be male type N connectors, and
must be sized according to the type of coaxial cable used. The GPS cable requires TNC male
and SMA male connectors. These connectors are available from a variety of manufacturers.
Important! All coaxial cable connections must be properly weather-proofed per
industry standards unless otherwise specified.
Mounting Hardware
Depending on your installation location and configuration, the installer must supply the following
mounting hardware to properly attach the collector or repeater to the mounting surface.
Caution: Since each installation is unique, you must ensure the mounting hardware
securely supports the collector or repeater. The collector or repeater (minus
attachment hardware) weighs 7 pounds. Itron recommends consulting with a qualified
engineer to verify load requirements and safety issues. Also, be sure to check and
comply with local codes when installing the collector or repeater.
